Temp control will not stay set at 0 / 37 degrees. It keeps getting colder. I replace the defrost thermostat & temp sensor in refrigerator with no luck. I'm thinking about replacing the main electronic control board please advise.
If it is the refrigerator section that the temperature is getting too cold then you will want to check the damper assembly to make sure that the door is not broken. If the door is broken you will want to replace part number WR49X10091.
No Power only inside lights work. Already replaced main board same thing?
Answer Steve, The interior lights are a direct circuit to the line cord, so as long as there's power to the refrigerator they should work. The Brown wire on the J11 terminal of the main control is the 120 VAC power into the control. You'll need to use a meter and check for the voltage on the wire terminal. It isn't likely that two different control boards would be defective, but it is possible. you'll need to get the wiring diagram and check for voltages in and out of the control board. Hopefully it's just a loose or broken brown wire.
